Pump failure shuts down Conn. nuclear power plant

WATERFORD, Conn. 
Officials are investigating why a cooling water pump in a reactor at a Connecticut nuclear power plant stopped unexpectedly during routine maintenance work, causing the reactor to automatically shut down.

Plant owner spokesman Ken Holt says the Unit 2 reactor shut down at 3:15 p.m. Sunday. It had not been reactivated by Monday evening.

The system will be restarted only after investigators figure out what caused the cooling water pump to shut down.

Diminion spokesman Holt says the federal Nuclear Regulatory Commission has been notified. The NRC keeps an inspector at the power complex.
